    Abstract: The bearings (32,34) of aircraft angle of attack (AOA) vanes (18) are susceptible to lightning strike damage, which causes fluting on the inner and outer races (40a,b,42a,b) of the bearings (32,34) and causes the bearings (32,34) to generate friction, noise, and vibrations. To prevent the bearings (32,34) from experiencing damage due to lightning strikes, the bearings (32,34), the shaft (26), and/or the mounting plate are configured to create an electric isolator (22) to prevent the electric current from the lightning strike from passing through the bearings (32,34), thereby preventing the bearings (32,34) from incurring lightning strike damage.

    Abstract: A methodology includes circulating a temperature-controlled and flow-rate-controlled medium (16) through a container (14) at a controlled flow rate and submerging a thermistor (12) with the medium. With the thermistor submerged, a power output of the thermistor is determined and compared to a power criterion, after which classification of the thermistor occurs based on a comparison of the power output to the power criterion. The methodology can include submerging a reference thermistor within the medium and determining a reference power output of the reference thermistor with the reference thermistor submerged within the medium, the power criterion determined based on the reference power output.

    Abstract: An angle of attack sensor 10 includes a vane that is freely rotatable to align with a direction of an oncoming airflow over the vane. The airfoil 14 includes a root proximate a vane hub 26 that connects to a rotatable shaft 54, a tip opposite the root, a leading edge 44, a trailing edge 46 opposite the leading edge 44, a first lateral face 42A, a second lateral face 42B, and a heating element disposed within the airfoil 14 between the first and second lateral faces proximate the leading edge 44. The first lateral face 42A extends from the leading edge 44 to the trailing edge 46. The second lateral face 42B is opposite the first lateral face 42A and extends from the leading edge 44 to the trailing edge 46. The first and second lateral faces are symmetric about a chord 48 of the airfoil 14 and each have an outer surface profile that is nonlinear and geometrically convex from the leading edge 44 to the trailing edge 46.

    Abstract: A system for determining a health status of a positive temperature coefficient resistor (PTCR) heater assembly (28) includes a PTCR heater assembly (28) and a health monitoring system (24). An input voltage is provided to the PTCR heater assembly (28) to provide heating. The health monitoring system (24) includes a first sensor configured to sense the input voltage at the PTCR heater assembly (28) and a second sensor configured to sense a current through the PTCR heater assembly (28). The health monitoring system (24) is configured to determine a baseline characteristic and an observed characteristic each relating to an inrush peak of the PTCR heater assembly (28) and based on the input voltage and the current. The health monitoring system (24) compares the observed characteristic to the baseline characteristic to assess a health status of the PTCR heater assembly (28) and outputs the health status for PTCR heater assembly (28) diagnostics and/or prognostics.
